I also had seen studies and stats on here which said that in mixed groups through school, college and work, men control a disproportionate amoutn of the conversation.
Wasn't there something about a college lecturer who made sure that the female students got as much floor time in a lecture as the males, and afterwards she asked him how they had found the session, and the men said that they didn't like that it had been dominated by women!
If that has changed that's great. Are there any links?
And OP. FFS on your DDs behalf, that's appalling.
Is a mixed group talking about feminism especially at this age going to yield positive results? I imagine a lot of girls might be put off talking about the sort of sexism they are likely to have experienced, at that age, those who have had stuff a lot of it will be around sexual type things. Certainly when I was that age the sexism I had experienced most, and was most angry about was street harassment, groping, being followed, wanked at, that kind of thing.
